+Subject: [PATCH] context: improve state calculations
+
+Always make peers of non-passive links runnable, even if we already
+visited the peer node. This makes non-passive links between drivers set the
+drivers to runnable. (midi-bridge, source to sink). It also makes nodes
+collected from the (link-)group runnable when they are linked together.
+
+To calculate the runnable state of the other nodes, only start from
+non-driver runnable nodes (like we already did when following links).
+
+This makes a link from echo-cancel-source to echo-cancel-sink activate
+the echo-canceler chain instead of staying idle.
